SHEET-METAL BOX.

To all whom it may concern Be itfknown that I, FREDERICK WESTER- BEoK, acitizen of the United States of America, residing in the city of St.Louis and State ..of Missouri, have invented certain new and usefulImprovements in Sheet- Metal Boxes, of which the following is a full,clear, and exact description, reference accompanying drawing, forming apart of this specification.

y invention relates to sheet metal boxes of the kind generally used ascontainers for shoe blacking and the like,and which are provided withslip covers. It is-highly desirable in making boxes of this descriptionto provide for the production of a close joint between the covers andthe bodies of the boxes to exclude air from access to the contents tocause evaporation or deterioration of such contents. The bodies of theboxes and the flanges of the covers are, therefore, so produced relativeto each other as to provide for the cover flanges fitting snugly andclosely to the .box bodies, which results in making it extremelydifficult at times to remove the covers, the difficulty beingparticularly increased in degree when the contents of the box are of anadhesive nature and enter into the joints between the covers and causingthem to adhere to each other. Furthermore,, such boxes are commonly,provided. with beads projecting outwardly from the walls of the boxbodies to serve as stops for the rim flanges of the covers and it istherefore difficult to insert sharp instruments, such as knives, betweenthe cover flanges and box bodies, as is the customary practice, toloosen the joint between them and permit the separathe bodies.

It is the object of my present invention to provide boxes of the type towhich I have referred with knife guiding means that will permit of theready insertion of knife blades, or other sharp instruments, between thecover flanges and the box bodies, such means being intended to provideonly for the initial insertion of the sharp instrument withoutmaterially affecting the air tight joint between these members, it beingobvious that after such initial insertion, the sharp instrument may bereadily moved in a circuit around the box between the coverSpecification of Letters Patent.

flange and the box body to complete their separation.

Figure I is an elevation of a sheet metal box embodying my improvement.Fig. II is an enlarged vertical cross section through fragments of'thebox.

ed to fit closely to the box body wall above its bead 2, and the loweredge of which is adapted 'to rest upon said head when thebox is closed.

To permit of the readv separation of the cover from thebox body, theflange 4 of said cover is provided with a short'and stiff downwardlyextending broad lip 5 that is only sufliciently offset from the flangeof the cover to permit the lapping thereof over the bead 9 of the boxbody when the cover is put in place on said body and which, due to thepresence of the head, has its lower edge held slightly separated fromthe box body wall. as seen in Fig. II. It will. be understood that aknife blade, or other sharp instrument, may be readily inserted back ofthe lip 5 due to its separation from the box body wall, and thencontinued upwardly between this lip and the bead 2 to pass between thecover flange and the body wall above the bead, subsequent to whichinsertion of the instrument, it may be quickly carried around the box inthe joint between the cover" and box body to loosen such joint andprovide for the easy removal of the cover.

I claim:

A box comprising a body having an annular wall rovided with an outwardlyjutting annu ar bead located beneath the top edge of said body and acover'having :1 depending flange, fitting closely to the body and to thebead, formed with a, short stiff knife guiding broad lip lapping theannular bead and having its edge projecting slightly beyond the bead.
